In this paper, we introduce an analytical model of CDMA reverse link power control based on the asymptotic theory. The effect of the SIR threshold value on the transient behavior is addressed and the optimal value of the threshold to achieve the fast convergence without oscillation is derived. In addition, the usefulness of the asymptotic analysis is confirmed by simulations.

This paper proposes a power control algorithm with fast convergence suited for wideband code division multiple access (WCDMA). Conventional algorithms are developed with continuous mode power control not binary mode power control. The new power control algorithm is suggested to support the binary mode power control and to offer the optimal relaxation factor for fast convergence.
